This Russian report seems to indicate that S.T.A.L.K.E.R. 2 may require a persistent internet connection to play. Here is a rough machine translation of the answer to a question about DRM in GSC Game World's upcoming first-person shooter sequel: "Protection from piracy? Part of the content will be located on the server and downloaded as the game progresses. We need constant access to the Internet. Will finish the text information, code and maximum game. Software piracy hurts us to beat, we fight with him, but in moderation. If people can not buy a licensed version, it is to our advantage, so he bought a pirate, and then wanted to buy a license. In Ukraine, there are different products that people love so much that he buys a license in principle. We want to create just such a product." Thanks RPS via Kotaku Aus/GSC.
